Abstract

Vibrational states and location of H atoms near two dimensional surfaces are not well known. In the present study, we successfully performed inelastic neutron scattering and obtained vibrational spectra of H in 8-nm-thick Pd films. While the vibrational spectra are similar to those in nanoparticles at low energy region, they are similar to those in bulks at high energy region. It is revealed that the vibrational states of H near flat surfaces are unique and have both characteristics of bulk and nanoparticle.
